Description
Technical field
The invention belongs to high current vacuum circuit breaker technical field, be specifically related to the vacuum interrupter of a kind of NEW TYPE OF COMPOSITE magnetic field structure of contact terminal and application thereof.
Background technology
Along with the development of electric power system, the application of vacuum circuit-breaker in whole electric power system is also developed fast.But in the process of development, the requirement for vacuum circuit-breaker is also continuous raising.In order to improve the short circuit interruption ability of vacuum interrupter, in arc control device, introduce the field control of electric arc.
Field control mainly includes transverse magnetic field control technology and longitudinal magnetic field control technology.Wherein, transverse magnetic field technology is by specific structure of contact terminal, the current path formed is formed at contact and contact gap region thereof flow to vertical transverse magnetic field with arc current in arcing process.Transverse magnetic field acts on vacuum arc, drives it in contact surface rotary motion, avoids the excessive ablation of electric arc for contact local, improves the connecting-disconnecting function of switch.Longitudinal magnetic field technology is also by structure of contact terminal, is formed and flows to parallel magnetic field with arc current.Longitudinal magnetic field technology makes vacuum arc more even, decreases gathering of vacuum arc, alleviates the ablation of electric arc for contact surface, improve the connecting-disconnecting function of switch.
In existing vacuum interrupter, longitudinal field contact structure is mainly cup-shaped and indulges magnetic structure of contact terminal and coil type indulges magnetic structure of contact terminal.Transverse magnetic field structure of contact terminal is mainly the horizontal magnetic structure of contact terminals of open flume type such as the horizontal magnetic structure of contact terminal of cup-shaped, fylfot.The advantage of longitudinal field contact structure is that the control ability of electric arc is strong, and connecting-disconnecting function is strong; Shortcoming is that structure of contact terminal is complicated, and structure of contact terminal conducting resistance is large, has larger restriction for rated current.The advantage of transverse magnetic field structure of contact terminal is that structure of contact terminal is simple, and contact conducting resistance is little, can the larger rated current of conducting; Shortcoming is under the effect of transverse magnetic field control technology, and vacuum arc, in fast rotational process, has certain ablation for contact, and the splash meeting of electric arc causes ablation to a certain degree to radome.In sum, respectively have quality in the application of existing horizontal and vertical magnetic field structure contact in circuit breaker, its structure is also at continuous Improvement and perfection.
At present, the research of resultant field structure of contact terminal also achieves certain development, the composite contact structural design scheme (EUROPEANPATENTAPPLICATION of especially ABB AB's proposition; Applicationnumber:11006056.3).The structure of contact terminal of its design as shown in Figure 1.Its structure of contact terminal forms primarily of outermost contacts structure 40 and inner side structure of contact terminal 52.Outermost contacts structure 40 is circulus, and slots in outside; Inner side structure of contact terminal 52 is the structure of contact terminal that diameter is less, is placed in the outermost contacts inside configuration of ring-type.By the design of its fluting, its outermost contacts structure 40 and inside contact structure 52 all can produce magnetic field, retrain and control vacuum arc.Outermost contacts structure 40 can form transverse magnetic field and longitudinal magnetic field by the cooperation in the direction of fluting; Inner side structure of contact terminal 52, by the cooperation in fluting direction, also can form transverse magnetic field and longitudinal magnetic field.
Above-mentioned composite contact structure, by the cooperation of outermost contacts and inner side contact, can form transverse magnetic field respectively--and longitudinal magnetic field combines; Transverse magnetic field--transverse magnetic field combines; Longitudinal magnetic field--longitudinal magnetic field combines.This structure of contact terminal, in arcing process, has given full play to the control for vacuum arc of transverse magnetic field and longitudinal magnetic field.If only consider the constraint of contact magnetic field for electric arc, above-mentioned structure of contact terminal, by being combined to form resultant field, being strengthened and takes full advantage of the control of horizontal and vertical magnetic field for electric arc.
But in the application of reality, above-mentioned resultant field structure of contact terminal is owing to being formed by outside ring-type contact and inner side minor diameter contact combinations, and the structure of contact surface is too complicated.Under conditions of high current, easily cause excessive ablation and the structural damage of contact surface, be unfavorable for cut-offfing under big current condition.

Resultant field structure of contact terminal of the present invention strengthens the transverse field strength of contact gap, optimizes the transverse magnetic field distribution of central area.Due to the cooperation of contact notching construction and angle, during arcing, arc current not only needs to produce transverse magnetic field through quiet end transverse magnetic field contact blade 103 and moved end transverse magnetic field contact blade 104, also through quiet end excitation structure of contact terminal 102 and moved end excitation structure of contact terminal 105, again to produce transverse magnetic field.This design, by the quiet end transverse magnetic field contact blade 103 of different-diameter and moved end transverse magnetic field contact blade 104 and quiet end excitation structure of contact terminal 102, the coordinating of moved end excitation structure of contact terminal 105, extends the circulation path of electric current in structure of contact terminal; Simultaneously by the cooperation of diameter, enhance the intensity of the contact gap particularly transverse magnetic field in contact center region.Compared with prior art, tool of the present invention has the following advantages:
1) contact surface structure is simple; Contact surface shape is the surface of open flume type transverse magnetic field contact blade, and surface texture is succinct; Because transverse magnetic field is for the action effect of vacuum arc, vacuum arc rotates ablation in contact surface, can cause ablation in contact surface; Simple contact surface structure can make ablation be evenly distributed, and is conducive to cut-offfing of high current arc.Compare existing resultant field contact, contact surface of the present invention is traditional " ten thousand " font or traditional horizontal magnetic contact surface completely.This contact surface is very simple, is more conducive to the even ablation of contact.
2) simple structure of contact terminal is utilized to define compound transverse magnetic field; In arcing process, arc current not only flows through contact surface, can flow through the excitation structure at the contact back side simultaneously.When arc current flows through above-mentioned two structures, all transverse magnetic field can be produced.Along with electric current flows through the increase of distance, the transverse magnetic field that the intensity of the transverse magnetic field of the superposition that two structures produce can produce than simple contact blade is stronger.Stronger transverse magnetic field just advantageously in the motion of horizontal magnetic contact electric arc, cut-offfing advantageously electric current.
3) more effectively make use of complicated structure of contact terminal; In existing design, when electric arc is in the zones of different of contact surface, the path that electric current flows through is different, or flows through outermost contacts, or flows through inside contact.When electric arc is in contact edges, the structure of contact inside does not in fact have too big current and flows through, and therefore only has the structure in outside to play a role yet.In the present invention, because contact surface is an entirety, no matter therefore where electric arc is in contact, the excitation structure of contact dorsal part is all have magnetic field to create.
4) distribution of traditional transverse magnetic field is optimized; Traditional horizontal magnetic contact, if electric arc is the central area ablation at contact, so due to electric current flow through distance under, the horizontal magnetic of contact gap is more weak.And in the present invention, because excitation structure of contact terminal diameter is little, in addition, no matter where electric arc is burning, excitation structure all can have electric current to flow through, and therefore produced transverse magnetic field supplements the deficiency of contact blade in magnetic field, central area.
